DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital image processing apparatus for reading a photographed image from a photographic film to generate digital photographed image data and recording the data on a recording medium for storage.

[0002]

2. Description of the Related Art In recent years, digital image processing has become familiar, and even in a DP shop, in a printing process from a photographed film that has been photographed, a photographed image obtained by reading a photographed image from a developed photographic film with a film scanner. A method of creating print data by performing image processing as needed on image data and then exposing photographic paper using this print data and a digital exposure device has appeared. I have. At that time, the captured image data obtained from the photographic film
A service has also emerged in which a recording medium such as -R or the like can be recorded and stored, and a customer who brings back the recording medium can organize and store the photographed images while viewing the images on a personal computer screen or send the images by e-mail. It is also possible to obtain a reprint without a photographic film by bringing a recording medium on which a photographic image to be reprinted is recorded to a DP shop even in a reprint that may occur at a later date.

[0003]

The digitalization of a photographed image of a photographic film into digital data and storing it on a recording medium provides many advantages as described above. Since only the captured image, which is a so-called frame image, is converted into digital data, other information of the photographic film, that is, so-called film information, is lost from the recorded contents of the recording medium. Typical film information is, for example, an APS (Advanced Photo System) film such as a film model number, a frame title, a print type, and exposure data written on a magnetic recording layer. DX code, film model number, etc. which are formed as the above.

[0004] If the print type is lost due to digitization of an image captured from the APS film, the print type initially performed at the time of additional printing becomes unknown, and it may occur that additional printing is not performed at the same print size as at the time of simultaneous printing. Also, film names and model numbers are important information, especially for enthusiast enthusiasts, and if there is no such film information on the recording media, a separate list will be created to compare captured image data with film information Must be kept beforehand, which leads to hesitation about saving the photographed image on the recording medium.

[0005] Further, as an additional problem relating to storage of a photographed image instead of photographic film in a recording medium,
When the photographed image data recorded on the recording medium is so-called raw photographed image data before the image processing for printing is performed, it is difficult to create a print of the same quality by reprinting afterwards. If the photographed image data recorded on the recording medium is so-called processed image data after performing image processing for printing, if the processing is irreversible, it is impossible to return to the original photographed image once Thus, when new image processing (including trimming) different from the previous one is newly performed, it is impossible or the image quality is reduced. Recording both raw captured image data and processed image data on a recording medium to avoid this problem is against the efficient use of the recording capacity.

In view of the above situation, it is an object of the present invention to prevent loss of film information when a photographed image of a photographic film is converted into a digital image. An additional object of the present invention is to provide a method of storing captured image data which is optimal for work such as printing at a later date.

[0007]

In order to solve the above-mentioned problems, a digital image processing apparatus according to the present invention comprises a film reading means for reading a photographed image and film information from a photographic film, and a film read by the film reading means. A photographed image data generating unit that generates photographed image data from a photographed image, a film information data generating unit that generates film information data from film information read by the film reading unit, and the photographed image data and the film information data. It comprises a formatter unit that creates a photographic image file in combination, and a recording device that records the photographic image file on a recording medium.

In this configuration, film information formed on a film as a latent image such as a 135 film, or film information recorded on a film as a magnetic code such as an APS film is read by film reading means and then read. The data generation unit converts the film information data into digital data by converting the film information data and the photographed image of the photographic film into digital data in a predetermined format to create a photographic image file and store it on an appropriate recording medium. Be recorded.
Therefore, since the photographed image data corresponding to one frame of the photographic film and the corresponding film information data are combined and recorded on the recording medium, by using an appropriate viewer, the recording medium can be read from the recording medium at any time. It is possible to display or print out the read photographic image and film information. That is, there is no loss of the film information in the recording medium storing the photographed image data by this device, and the film information can be freely used.

Further, as one of preferred embodiments of the present invention, an image processing section for performing various image processing on the photographed image data in order to generate print data from the photographed image data, An image processing history data generating unit that generates a history of image processing performed by the unit as image processing history data, wherein the formatter unit is configured to incorporate the image processing history data when creating a photographic image file There is. In this configuration, image processing history data indicating the history of image processing performed on so-called raw photographed image data is incorporated into the photograph image file together with the photographed image data and the film information data. By always performing image processing on the captured image data based on the contents of the image processing history data, it is possible to generate the same print data as that used at the time of the first print, and as a result, the first print It is also possible to create an additional print having the same quality as that of the first embodiment, in particular, a color print state.

In performing a trimming process that is important for photographic printing as part of image processing, the image processing unit defines a trimming frame for the photographed image data, as proposed as a preferred embodiment of the present invention. A trimming data generating unit for generating trimming data is linked, the image processing unit generates the print data from the area of the photographed image data determined by the trimming frame, and the trimming data is the image processing history data. If a configuration that can be incorporated into the photo image file is adopted, the trimming data that defines the set trimming frame is incorporated in the photo image file, so if you want to restore or correct the trimming at a later date, Trimming data and captured image data Using data, to restore the previous trimming frame, based on the restored previous trimming frame, it is possible to modify the trimming.

When the digital image processing apparatus handles a photographic film provided with film information in the form of a latent image, such as a 135 film, the reading means converts the photographic film from the photographic film to a photographed image and film information as film information. A film scanner for reading the latent image may be provided. Particularly preferably, adopting a configuration in which the photographed image and the latent image are simultaneously read by a single film scanner can provide advantages in terms of control cost and arrangement space.

Further, the digital image processing apparatus includes:
In the case of handling a photographic film provided with film information in the form of a latent image, such as a film 5, the reading means reads a photographed image from the photographic film and a film information from a magnetic recording layer of the photographic film. It is preferable to provide a magnetic head for reading film information. However, in most cases, it is necessary to handle both films, so that both a magnetic head for reading film information and a film scanner for reading a latent image are provided. However, when this digital image processing apparatus is incorporated into a silver halide photographic printer called a digital minilab, a magnetic head for reading film information and a latent image in any case for setting parameters such as exposure control are used. Since both of them are provided with a film scanner for reading, they can be used in combination. Other features and advantages according to the present invention will become apparent from the following description of embodiments with reference to the drawings.

Is disposed upstream of the exposure area where the digital print section 5 is disposed in the photographic paper transport direction. Of course, the back print unit 4 may be arranged downstream of the exposure area.

In consideration of a relatively short exposure time and a long development time for the photographic paper 2, the photographic paper transport mechanism 9 is a single line of photographic paper transport line up to the exposure area 15, and the development processing unit 6
A photographic paper transport line capable of transporting the photographic paper 2 in three rows from is formed. For this reason, between the exposure area and the development processing section 6, there is provided a sorting device 13 for sorting the exposed photographic paper 2 from single-row conveyance to double-row conveyance up to three rows.

The film scanner 3A includes, as main components, an illumination optical system 31, an imaging optical system 32, and a line CCD.
The photoelectric conversion unit 33 using the sensor determines the irradiation range of light to the film 1 and connects the film 1 to the line CC.
An automatic film mask 80 is provided for conveying in the sub-scanning direction for scanning by the D sensor. The auto film mask 80 is prepared for each type of film such as 135 film, APS film, and Brownie film. Therefore, the above-described magnetic head 3B has the APS
It is provided on a film mask 80 for a film.

The illumination optical system 31 includes a halogen lamp 31a as a white light source, a dimming filter 31b, a mirror tunnel 31c, etc., and irradiates the film 1 with the light beam from the light source having a uniform color distribution and intensity distribution.

b.

The photoelectric conversion unit 33 for photoelectrically converting the light beam guided by the imaging optical system 32 includes three CCD sensors 33 assigned to detect each color of RGB.
a, 33b, and 33c. Each CCD sensor is a line sensor in which a large number (for example, 5000) of CCD elements are arranged in the main scanning direction, that is, in the width direction of the film 1. The charge storage operation and the control of the charge storage time are performed. A color filter that allows only the red component of the light transmitted through the film 1 to pass through the imaging surface of the red CCD sensor 33a, and allows only the green component of the light that has passed through the film 1 to pass through the imaging surface of the green CCD sensor 33b. A color filter is provided on the imaging surface of the blue CCD sensor 33c so as to pass only the blue component of the light transmitted through the film 1, and photoelectrically converts only the blue component, the red component, and the green component, respectively. . Each pixel signal output from each CCD sensor is sampled and held, and each pixel signal becomes a continuous image signal. Each pixel signal is converted into a digital signal having a predetermined number of bits (for example, 12 bits).

The auto film mask 80 shown in a sectional view in FIG. 3 includes a base member 80a located below the film 1 to be conveyed and a cover member 80b located above the film 1 to be conveyed. And a base member 80a and a cover member 80 for constituting the film transport mechanism 8.

Further, a through-hole forming block 8 that guides light emitted from the illumination optical system 31 and transmitted through the film 1 to the imaging optical system 32 as slit light is provided on the base member 80a.
1 is provided. An opening is formed in the cover member 80b so as to guide the light exiting the mirror tunnel 31c to the film surface.

As shown in FIGS. 3 and 4, the through-hole forming block 81, which functions as a shielding member for shielding light so that unnecessary light does not enter the CCD sensor, is provided in a transverse direction perpendicular to the film transport direction. Along the axis of the illumination optical system 31 so as to coincide with the optical axis of the illumination optical system 31.
Are formed. The width of the passage hole 81a is about 1 mm, and the length thereof is set to be longer than the width of the film 1.
Light transmitted through the edge image area 1b where an edge image such as a film maker name or a frame number located in the edge area of the film 1 is formed through the imaging optical system 32 to the photoelectric conversion unit 33. Can be reached.
The reason why the length of the passage hole 81a is set to be longer than the width of the film 1 is to take into consideration the meandering of the film 1 during transportation that may occur in some cases. Information (film maker name, frame number, etc.) recorded in the edge image area 1b partitioned outside the image area 1a can be reliably read together with the photographed image.

As is apparent from FIG. 5, both ends of the film 1 having a curl so as not to enter the passage hole 81a longer than the width of the film 1 during scanning conveyance. Here, a light transmitting member 82 made of glass is buried in a portion corresponding to the edge region 1b. The light transmitting member 82 is processed into a disk shape, and is fitted in a cylindrical concave portion provided in the through hole forming block 81 so as to expose a circular end surface on the film transport surface. The corner of the light transmitting member 82 is chamfered, and one side of the circular end face is made to correspond to the level of the film transport surface. Light transmitting member 8
A light reducing layer 82a is formed on the other side of the circular end face of No. 2, that is, on the side not in contact with the film 1 by silver or aluminum vapor deposition (see FIG. 3).

Since the light transmitting member 82 is positioned so as to overlap the film information area 1b of the film 1 in the optical axis direction, the light reducing layer 82a of the light transmitting member 82 is formed.
Reduces the light having a strong light amount that has passed through the transparent portion of the film 1 or the outside of the film 1, and prevents an excessive amount of light from reaching each CCD sensor of the photoelectric conversion unit 33.

A guide roller 8b that supports the lower surface of the film 1 is disposed upstream and downstream of the scanning line SL defined by the center line of the through hole 81a formed in the transmitted light forming block 81 in the film transport direction. The guide roller 8 b is rotatably supported by the base member 80 so as to be embedded in a groove provided in the passage hole forming block 81. The running property of the film 1 passing through the scanning line SL is improved by the guide rollers 8b.

As can be clearly understood from FIG. 3, at least a portion of the passage hole 81a corresponding to the photographed image area 1a has an hourglass-shaped cross section in which the vertices of a small inverted triangle and a large triangle are connected. And the narrowest width is a connection point of two triangles. The cross-sectional shape may be determined so that the light transmitted through the film is focused on the three CCD sensors 33a, 33b, and 33c constituting the photoelectric conversion unit 33. This 3
The three CCD sensors 33a, 33b, and 33c are arranged in three lines so as to be orthogonal to the transport direction of the film 1. The main scanning of film scanning is performed in the arrangement direction of the CCD elements constituting each CCD sensor. 1
Is conveyed to perform sub-scanning.

When the film 1 is positioned at the predetermined scanning position, the reading process of the film image is started, and the transmitted light of the film image is sequentially sent to the three CCD sensors 33a, 3
3b and 33c, the CCD sensors are arranged at intervals of several pixels along the transport direction of the film 1, so that R, G, and B in the same pixel are read.
There is a time difference between the detection timings of the respective component colors, but this is caused by the signal processing in the subsequent stage of the photoelectric conversion unit 33, in which the R, G, and B image signals of the same pixel are associated with each other and stored in a predetermined memory of the controller 7. Is stored.

When the film 1 to be scanned is an APS film having a magnetic recording layer, the magnetic head 3B operates in conjunction with the feeding of the film 1 by the film transport mechanism 8 to record the film information recorded on the magnetic recording layer. Read. Such an illumination optical system 3 of the film scanner 3A
